In Santa's Bag, you play an Elf in Santa's workshop. You make toys for kids!
Santa reads his list and tells the Elves what toys to make and who will get them. On your turn, look at the toys that need to be made. Do you have the parts to make a toy? Do you need more parts? You can trade with other Elves to get a part. You can even use Elven Magic to make the right part!
The trickier the toy, the more points you earn. Building toys for nicer children earns you even more points!
When you've built all the toys on Santa's list, the player with the most points wins!
